The hello module in the wiki does not support any open,read,write,close operationing functions. So you cannot do any operations on it. It is only a very simple module, with only init and exit. You should follow the book "Linux Device Driver" to get more examples.

Microtronix stated "not for kernel development" in their guide. You should really move to Linux PC. You have to learn Linux before you can develope Nios2 uClinux. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif
